OpenAI Acquires Promptfoo to Bolster AI Agent Security

OpenAI announced that it has acquired Promptfoo, a security startup founded in 2024 that protects large language models from adversarial attacks. The deal will integrate Promptfoo’s testing tools into OpenAI Frontier, the company’s enterprise platform for AI agents. Promptfoo, created by Ian Webster and Michael D’Angelo, already serves a significant share of Fortune 500 firms and has raised $23 million. OpenAI said the technology will enable automated red‑teaming, workflow security checks, and risk monitoring for its agentic products, while continuing to support Promptfoo’s open‑source offerings.

Users Switching from ChatGPT to Claude Encounter Usage Limits and New Trade‑offs

A wave of users is moving from ChatGPT to Anthropic's Claude after OpenAI announced a Pentagon partnership. While Claude has gained popularity, new adopters are surprised by its different interface, stricter usage caps, and tiered model offerings. The free plan is tight, and even the $20 paid plan can run out of capacity quickly on the most powerful Opus model. Anthropic’s business strategy targets higher‑paying business customers rather than mass‑market users, leading to a contrast with OpenAI’s broader approach. The limits spark debate over cost, user experience, and the broader impact of unrestricted AI access.

Pentagon‑Anthropic Contract Dispute Highlights AI Governance Gap

A clash between the U.S. Department of Defense and AI developer Anthropic over the use of the Claude model exposed a regulatory vacuum. The Pentagon sought unrestricted access for "all lawful purposes," while Anthropic drew red lines against domestic surveillance and fully autonomous weapons. After Anthropic refused, the administration labeled the firm a supply‑chain risk, prompting a lawsuit. Experts say the episode underscores the need for clear congressional rules on AI in national security, as the military pivots to OpenAI and the broader debate over AI‑driven surveillance and weaponry intensifies.

Anthropic Sues U.S. Government Over Supply‑Chain Risk Designation

Anthropic has filed a lawsuit in a California district court alleging that the U.S. government illegally labeled the AI firm as a supply‑chain risk and ordered all federal agencies to stop using its technology. The company claims the designation, issued by the Trump administration, violates its First and Fifth Amendment rights and exceeds executive authority. The suit follows a series of agency cutoffs, including the General Services Administration terminating its contract, and a broader controversy over the Pentagon’s use of Anthropic’s AI models. Anthropic says it will challenge the designation in court while its major partners continue limited collaborations.

OpenAI CEO Sam Altman Hails GPT-5.4 as Favorite Model While Acknowledging Three Key Weaknesses

OpenAI chief Sam Altman praised the new GPT-5.4 model as his favorite version to converse with, highlighting improvements in personality and coding ability. He also recognized three shortcomings—frontend aesthetic taste, occasional lapses in real‑world context, and incomplete task execution—that the company plans to address. The remarks underscore OpenAI’s shift toward refining how ChatGPT feels to use, not just its raw performance, as it competes with rivals such as Claude, Gemini and Opus.

Anthropic Sues U.S. Government Over Supply Chain Risk Designation

Anthropic has filed a lawsuit to block the Pentagon from adding the AI firm to a national‑security blocklist after the Department of Defense labeled it a supply‑chain risk. The company argues the designation violates free‑speech and due‑process rights and lacks statutory authority. The legal action follows weeks of tension with the Defense Department, which pressed Anthropic to remove safeguards against mass surveillance and autonomous weapons. Anthropic’s CEO Dario Amodei refused, leading to threats of contract cancellation and a broader government push to bar the firm from federal use. OpenAI later secured a deal with the Defense Department, emphasizing similar safety principles.
